Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This E.P. patent application claims priority to and the benefit of Chinese patent application number 201821089000.3, filed July 10, 2018, the entire disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

[0002] The present disclosure generally relates to a swimming machine for generating a directed water flow in a swimming pool.

2. Related Art

[0003] This section provides background information related to the present disclosure which is not necessarily prior art.

[0004] Swimming is a low-impact form of exercise that is popular among a wide range of people. Unfortunately, a limiting factor for people who may be interested in swimming as a form of exercise is that, generally speaking, a pool is needed that is large enough to allow a swimmer to be able swim in one direction long enough to require a substantial physical effort. A swimming pool meeting even minimal requirements will have a length up to several meters, with high cost, and requiring a huge volume of water. Moreover, public swimming pools have a potential risk for safety and health via overcrowding. As such, personal and public swimming pools have significant disadvantages on user experience since they cannot meet the requirement for long distance swimming due to a limited area, an occupied area, high costs, and the like.

[0005] In order to address the above issues, swimming machines have been developed that can be mounted in a personal swimming pool and produce a directed water flow with high speed. As such, a swimmer can swim against the directed water flow to achieve a desired amount of physical exertion even in a small pool. One common problem with traditional swimming machines is adapting them to various sized swimming pools. A user needs to adjust the height of the swimming machine and the distance between the wall of the swimming pool and the swimming machine. However, traditional swimming machines include a complicated structure and high cost.

[0006] Thus, there is a continuing desire to improve functionality and costs associated with swimming machines that generate a directed water flow.

SUMMARY OF THE INVENTION

DESCRIPTION OF THE ENABLING EMBODIMENT

[0012] The exemplary embodiments of the present disclosure are described below with reference to the drawings for illustration. It should be understood that the description of the exemplary embodiments are merely illustrative of the structure and the principle of the swimming pool, and the present disclosure is not limited to the exemplary embodiments. The drawings and the detailed description should be considered as illustrative of the present disclosure but not limiting the scope of present disclosure.

[0013] The terms regarding orientation such as "above", "below", "front", "back" and "side" and the like refer to relative orientation or direction and are used when the swimming machine is in use.

[0014] As shown in Figure 1, a swimming machine 1 is provided according to an exemplary embodiment as described herein. The swimming machine 1 comprises a body 11, an adjusting assembly 12, a hanging assembly 13 and a supporting assembly 14. As shown in Figures 1 and 4A, the body 11 comprises a water driver 112 and a housing 111 adapted for receiving and at least partially enclosing the water driver 112 and having a fluid inlet 1111 and a fluid outlet 1112. The adjusting assembly 12 is disposed above and coupled to the housing 111. The hanging assembly 13 is coupled to the adjusting assembly 12 and adapted for hanging on an upper edge of the pool. The supporting assembly 14 is independent of the adjusting assembly 12 and coupled to the housing 111, which is disposed below the hanging assembly 13 and abutted against an inner wall of the pool to support the body 11.

[0015] In particular, the fluid inlet 1111 is disposed at the side and/or back of the housing 111. The fluid outlet 1112 is disposed at the front of the housing 111. The water driver 112 comprises a motor 1121 and an impeller 1122, as best shown in Figure 4A. Fluid flows into the housing 111 via the fluid inlet 1111 and is pressurized by the motor 1121 and the impeller 1122 and directed outwardly at a highspeed (directed water flow), which flows out from the fluid outlet 1112.

[0016] As shown in Figure 2, in another exemplary embodiment described herein, a buffering member 15 is disposed between the body 11 and the adjusting assembly 12 for exhibiting buffering or a dampening effect if and when the body 11 moves relative to the adjusting assembly 12. When the swimming machine 1 is mounted to the pool 2, the hanging assembly 13 is hanged on an upper edge of the pool 2 and further fixed to the outer wall of the pool 2 by a mounting member 16, as shown in Figure 3. The adjusting assembly 12 includes a control interface 20 (see Figure 1 and Figure 2) for changing at least one setting of the water driver 112. The control interface 20 may be attached to the adjustment assembly 12 such that it can stay out of the water while the housing 111 is moved to a preferred depth. The buffering member 15 is shown to at least partially enclose an adjustable connector 30 that connects the adjusting assembly 12 and the housing 111.

[0017] In the exemplary embodiment as described herein, the hanging assembly 13 comprises a hanging recess 131 for allowing the upper edge of the pool to fit therein and a fastener 132 passing through the hanging recess 131 to fix the hanging recess 131 and the upper edge of the pool together. The fastener 132 can be a bolt or any other suitable mechanical members.

[0018] In this exemplary embodiment, the adjusting assembly 12 comprises an adjusting body 121 and a first connector 122 coupled to the adjusting body 121. The body 11 includes a housing 111 and a second connector 123 coupled to the first connector 122. The first connector 122 and second connector 123 are configured to move relative to one another to adjust the height of the body 11. The first connector 122 and the second connector 123 are part of the adjustable connector 30.

[0019] While not limited thereto, the adjusting assembly 12, according to the exemplary embodiments, is shown to be implemented in three different examples. Figures 4A to 5B show a first embodiment of the adjusting assembly 12. In particular, the first connector 122 can be detachably coupled to the second connector 123, both of which can be separated from each other when the second connector 123 moves from top to bottom relative to the first connector 122.

[0020] Still referring to the exemplary adjusting assembly 12 shown in Figures 4A and 4B, the first connector 122 is fixedly coupled to the adjusting body 121 and comprises multiple pairs of grooves 1221 arranged from top to bottom. The second connector 123 comprises a supporting part 1231 and paired sliding blocks 1232 disposed on the top of the supporting part 1231, as well as a first spring 1233 disposed between the paired sliding blocks 1232. The paired sliding blocks 1232 are configured to be separated from any one of the multiple pairs of grooves 1221 by compressing the first spring 1233 and to be engaged with any one of the multiple pairs of grooves 1221 by releasing the first spring 1233.

[0021] The supporting part 1231 is provided with a guiding part 1234 for the sliding blocks which is located on the top of the supporting part 1231 to allow the paired sliding blocks 1232 to stably slide on the top of the supporting part 1231. The guiding part 1234 for the sliding blocks is configured to receive the paired sliding blocks 1232 and the first spring 1233 and to guide the paired sliding blocks 1232 to press or release the first spring 1233 along the direction of the guiding part 1234 for the sliding blocks. In an alternative embodiment, the guiding part 1234 for the sliding blocks can be disposed below the paired blocks to act as a guideway or channel for the paired sliding blocks 1232.

[0022] The second connector 123 further comprises a driving part 1235 for the sliding blocks with protrusions 12351 at both sides of the top thereof and a controlling part 12352 at the bottom thereof. A recess 12353 with a narrow top and a wide bottom is defined between the protrusions 12351 as the protrusions include at least one angled cam surface 123511 (as numbered in Figure 4B). At least one of the paired sliding blocks 1232 comprises a sliding block hollow part 12321. The supporting part 1231 includes a supporting hollow part 12311 (as shown in Figure 5B). The driving part 1235 for sliding block is configured to pass through the supporting hollow part 12311 from the bottom of the supporting part 1231 to allow the protrusions 12351 to protrude through the sliding block hollow part 12321. The controlling part 12352 is disposed on the bottom of the supporting part 1231 and is configured to control the protrusions 12351 to drive the paired sliding blocks to press or release the first spring 1233 via upward and/or downward movement of the protrusions 12351 as the angled cam surface 123511 contacts and moves at least one of the paired sliding blocks 1232.

[0023] As best shown in Figures 4B, 5A, and 5B, the second connector 123 further comprises a holding part 1236 that is disposed between the housing 111 and the controlling part 12352. A second spring 1237 is disposed between the holding part 1236 and the controlling part 12352. The holding part 1236 comprises a holding groove 12361 for fitting a user's hand. When the user holds the holding part 1236 and presses the controlling part 12352 downward, the second spring 1237 is pressed and the protrusions 12351 and angled cam surface 123511 move downward to exert an inclined external force on the paired sliding blocks sideways, so as to drive the paired sliding blocks 1232 towards one another and compress the first spring 1233 until the paired sliding blocks 1232 are separated from any one pair of grooves 1221. Then the body 11 coupled to the second connector 123 can be moved upward and downward as needed. Upon moving the body 11 to a suitable position, the controlling part 12352 is released and recovered to the original location under resilience of the second spring 1237. The paired sliding blocks 1232 are also released by the protrusions 12351 to further release the first spring 1233 to bias and engage with any one of the remaining grooves 1221, thereby fixing the body 11 to a pre-set height or pool depth. In this example, the protrusions 12351 have a cross-section of a right-angled trapezoid. In an alternative example, the protrusions 12351 can be in any other suitable shape, as long as the recess defined by the protrusions 12351 is in a shape with a narrow top and a wide bottom or vice versa. In the present embodiment, the controlling part 12352 is a plate with anti-slipping strips on the surface thereof. In an alternative example, the controlling part 12352 can be in any other suitable shape without anti-slipping strips on the surface thereof. It should also be appreciated that in alternative embodiments, the holding part may be omitted.

[0024] Still referring to Figures 4B, 5A, and 5B, the second connector 123 may further comprise an external cover 1238 for fixing on a top of the supporting part 1231 and receiving the protrusions 12351, the paired sliding blocks 1232, the guiding part 1234 for sliding block and the first spring 1233. The external cover 1238 comprises a cover groove 12381 for allowing the paired sliding blocks 1232 to pass therealong.

[0025] Figures 6A through 6D show a second embodiment for the adjusting assembly 12. The adjusting assembly 12 of this embodiment is different from the one of the first embodiment in that a modified recess 12353 includes a wide top and a narrow bottom that can be defined between protrusions 12351. Similarly to the previous embodiment, the controlling part 12352 is configured to move upward by controlling the protrusions 12351 to drive the paired sliding blocks 1232 to press or release the first spring 1233. Other members may be the same as those of the first embodiment. In this case, the holding part and the second spring may be omitted. The controlling part 12352 has a hollow part for ease of operation by a user. Figures 6A and 6B show engagement of the paired sliding blocks with any pair of grooves 1221. Figures 6C and 6D show separation of the paired sliding blocks from any pair of grooves 1221. When the controlling part 12352 drives the driving part for sliding block to move upward, the protrusions 12351 move upward to drive the paired sliding blocks 1232 to press the first spring 1233 until the paired sliding blocks 1232 are separated from any pair of grooves 1221. As shown in Figures 6C and 6D, the body 11 coupled to the second connector 123 moves upward or downward as needed upon release of the sliding blocks 1232. Upon moving the body 11 to the suitable position, the controlling part 12352 is released to the original location under gravity or a spring. The paired sliding blocks 1232 are released by the protrusions 12351 to further release the first spring 1233 and engage with any one of the pair of grooves 1221, thereby fixing the body 11 to a pre-set height or pool depth. In this exemplary embodiment, the protrusions 12351 have a cross-section of a right-angled trapezoid. In alternative embodiments, the protrusions 12351 can be in any other suitable shape as long as the protrusions 12351 define the recess with a wide top and a narrow bottom or vice versa.

[0026] In an alternative embodiment, no controlling part is needed. More specifically, separation or engagement of the paired sliding blocks 1232 from/with any pair of grooves 1221 can be achieved by arranging the driving part 1235 for the sliding blocks, which can move upward and downward, arranging the protrusions 12351 on the top of the driving part 1235 for sliding blocks and arranging the spring on the bottom of the driving part for the sliding blocks. In this configuration, the user can manually and directly drive the protrusions to move upward (e.g., the protrusions define a recess with a wide top and a narrow bottom, and the spring is tensioned) or move downward (e.g., the protrusions define a recess with a narrow top and a wide bottom and the spring is compacted) to drive the paired sliding blocks to press the first spring along the direction of the guiding part for the sliding blocks, which in turn results in separation of the paired sliding blocks from any of the pair of the grooves. The body 11 coupled to the second connector 123 moves upward and downward, as needed. Upon moving the body 11 to a suitable location, the protrusions 12351 are released and return to the original location under resilience of the spring. At the same time, the paired sliding blocks 1232 are released by the protrusions 12351, which are engaged with any pair of remaining grooves to fix the body 11 to a pre-set height or pool depth. It should be appreciated that in other alternative embodiments, separation or engagement of the paired sliding blocks from/with any pair of grooves can be achieved by other arrangements without departing from the scope of the subject disclosure.

[0027] Figures 7 through 9B show a third embodiment of the adjusting assembly 12. The adjusting assembly 12 of this embodiment is different from those of the above examples in that the first connector 122 is configured to drive the second connector 123 to move upward or downward by rotation. More particularly, the adjusting body 121 has a perforated body opening 1211, through which the bottom of the first connector 122 passes through to be in threaded connection with the second connector 123. The top of the first connector 122 is fixed to the body opening 1211. The first connector 122 is configured to rotate around an axis of the body opening 1211 with respect to the adjusting body 121 to drive the second connector 123 to move upward or downward based on the direction of rotation.

[0028] A radial protrusion 1222 is disposed on the top of the first connector 122, which can be fixed to the body opening 1211. The radial protrusion 1222 has a diameter greater than that of the body opening 1211 to prevent the first connector 122 from moving downward during rotation. The adjusting body 121 comprises a first fixing member 1212 that is configured to rotatably fix the radial protrusion 1222 to the body opening 1211 and to prevent the first connector 122 from moving upward. In this example, the body opening has a stepped shape. In an alternative embodiment, the body opening can be in any other suitable shape and the first connector and/or the adjusting body can be rotated relative to the second connector to drive the second connector to move upward or downward by any other suitable arrangements.

[0029] As shown in Figures 8A and 8B, the adjusting body 121 further comprises a connector guiding part 1213 to allow the second connector 123 to stably move upward or downward relative to the first connector 122. The connector guiding part 1213 passes through the body opening 1211, through which the bottom of the first connector 122 passes to insert into the connector guiding part 1213. The top of the second connector 123 is configured to insert into the connector guiding part 1213 to be in threaded connection with the first connector 122. In an alternative embodiment, the second connector can be coupled to the first connector by any other suitable mechanical connection, as long as the second connector can move upward or downward relative to the first connector.

[0030] As shown in Figures 9A and 9B, the adjusting assembly 12 further comprises a limiting member 124 to limit the distance for downward movement of the second connector 123 relative to the first connector 122 and prevent detachment during lowering. The limiting member 124 is coupled to the second connector 123, with a limiting protrusion 1241 on the top thereof. The adjusting body 121 further comprises a receiving part 1214 comprising an engaging part 1215 for limiting protrusion and allowing the limiting member 124 to insert therein and move upward and downward. The engaging part 1215 for the limiting protrusion is configured to engage with the limiting protrusion 1241 once the limiting member 124 has been lowered to a predetermined height, so as to prevent the limiting member 124 from becoming detached.

[0031] As shown in Figure 10, the supporting assembly 14 comprises a supporting member 141 and a sliding member 142 coupled to the supporting member 141 at the back thereof. The housing 111 has guiding parts 143 for sliding member at the back and side thereof. The front of the sliding member 142 moves forward and backward along the guiding part 143 for the sliding member. The supporting assembly 14 further comprises a second fixing member 144 (or slide fixing member) configured to fix the sliding member 142 to a pre-set (i.e., predetermined) location, on which the supporting member 141 is in contact against the inner wall of the pool. The further the sliding member 142 is extended, the greater the downward angle of directed water flow.

[0032] The supporting assembly 14 will be described below in detail according to three nonlimiting exemplary embodiments. In the first and second embodiments of the supporting assembly 14, the second fixing member 144 is disposed at the front of the sliding member 142. A side opening 1113 is disposed at the side of the housing 111, which is arranged parallel to the guiding part 143 for sliding member. The second fixing member 144 is configured to fix the sliding member 142 to a pre-set location through the side opening 1113.

[0033] Figures 10 to 13 show the first embodiment for the support assembly 14. As shown, the second fixing member 144 comprises an elastic stopping part 1442 and a pressing part 1441 disposed above the elastic stopping part 1442. Pressing the pressing part 1441 causes corresponding deformation and compression of the elastic stopping part 1442. The pressing part 1441 is configured to protrude from the side opening 1113 (as shown in Figure 13) and slide with the sliding member 142 to be accessible to a user. The side opening 1113 has a stopping engaging part 11131 for engaging with the elastic stopping part 1442 to stop sliding of the sliding member 142. The elastic stopping part 1442 is also configured to separate from the stopping engaging part 11131 under pressure by the pressing part 1441 to allow the sliding member 142 to slide forwards and backwards. As shown in Figure 10, the stopping engaging part 11131 is a groove disposed on the bottom of the side opening 1113. In an alternative example, the stopping engaging part 11131 can be a groove on the top of the side opening 1113, or can be multiple grooves on the top and bottom of the side opening 1113. The guiding part 143 for sliding member comprises a guiding opening 1431 at the back of the housing 111 and a side guiding part 1432 corresponsive to the guiding opening 1431, which continuously extends from the back to the front of the side of the housing 111. In an alternative embodiment, the side guiding part can be discontinuous, as long as it is corresponds to the guiding opening and is adapted for guiding the sliding member to move forward and backward.

[0034] The second fixing member 144 further comprises a pressing supporting part 1443 configured to protrude from the side opening 1113 (as shown in Figure 13) and slide with the sliding member 142, which is disposed at the front of the pressing part 1441. As such, the pressing part 1441 is supported by the pressing supporting part 143 when the pressing part 1441 presses the elastic stopping part 1442. The pressing supporting part 1443 is shaped to be easy to grasp by a user in order to operate the pressing part 1441. As shown in Figures 10 and 11B, the pressing supporting part 1443 is illustrated with a narrow external portion and wide internal portion that allows the internal side to be located within the housing 111 and protected from environmental harms. The external side 14431 protrudes from the side opening 1113. In this example, as shown in Figures 11A through 11C, the pressing supporting part 1443 has an external side and an internal side having a rectangle shape. In an alternative example, the pressing supporting part can be in any other suitable shape. In an alternative embodiment, the internal side of the pressing supporting part can have the same width as that of the external side. In another alternative example, no pressing supporting part is included.

[0035] Figures 14 through 16B illustrate a second embodiment for the supporting assembly 14. The difference between the supporting assembly 14 in this example and the one in the first embodiment will be described below. Referring initially to Figures 14 through 16A, the recess which acts as the stopping engaging part within the side opening 1113 is omitted. The side guiding part 1432 of the guiding part 143 for the sliding member can be discontinuous or continuous. The second fixing member 144 is shown with a modified configuration different than the previous embodiment. In this embodiment, the second fixing member 144 comprises a rotation part 1444, a rotation rod 1445 protruding from the rotation part 1444, a rotation limiting part 1447, and a third spring 1446 sleeved on the rotation rod 1445 and being disposed between the rotation part 1444 and the rotation limiting part 1447. The sliding member 142 has an engaging part 1421 (or rotation engaging part 1421) for the rotation rod at the front thereof. When the rotation part 1444 is rotated to the rotation limiting part 1447 and snapped into the side opening 1113, the rotation rod 1445 is engaged with the engaging part 1421 for the rotation rod in order to prevent further sliding of the sliding member 142. In this example, the rotation limiting part 1447 may exhibit deformation and can be snapped into side opening 1113 by producing deformation, as shown in Figure 16A.

[0036] As shown in Figures 16A and 16B, external threads are disposed on the outer surface of the rotation rod 1445 and the engaging part 1421 for the rotation rod includes an opening at the front of the sliding member 142, which is correspondingly threaded to receive the rotation rod 1445. In particular, internal threads are disposed on the inner surface of the engaging part 1421 for the rotation rod, which are corresponding to the external threads of the rotation rod 1445. When the sliding member 142 slides to a pre-set position, the rotation part 1444 can be rotated to the rotation limiting part 1447 to exhibit deformation so as to be snapped into the side opening 1113. Meanwhile, the external threads of the rotation rod 1445 can match with the internal threads of the engaging part 1421 for the rotation rod, thereby stopping sliding of the sliding member 142 and allowing the supporting member 141 to contact against the inner wall of the pool such that the directed water flow is at a desired angle. In order to adjust the position of the supporting member 141, the rotation part 1444 is rotated to the rotation limiting part 1447 to detach from the side opening 1113 such that the external threads of the rotation rod 1445 are separated from the internal threads of the engaging part 1421 for the rotation rod. As such, the sliding member 142 drives the supporting member 141 to move forward or backward to other positions along the guiding part 143 for the sliding member. In an alternative embodiments, the rotation rod can be detachably coupled to the engaging part 1421 for the rotation rod by other mechanical connection means.

[0037] Figures 17A through 19D show a third embodiment for supporting assembly 14. In addition to details about the third embodiment, differences between the third embodiment and other examples will be described. Referring initially to Figures 17A and 17B, the supporting assembly 14 further comprises a supporting rod 145 mounted at the back of the housing 111 and having a first ratchet 1451 and a second ratchet 1452 which are adjacent to each other. The second ratchet 1452 is disposed outside of the first ratchet 1451. The sliding member 142 in this embodiment is modified from the one in the first embodiment in that the sliding member 142 has a hollow part with a third ratchet 1422 disposed therein, adapted for engaging with the first ratchet 1451, wherein the second ratchet 1452 is disposed outside of the hollow part. The first ratchet 1451 and third ratchet 1422 are shown as a rack-and-pinion type connection.

[0038] When the sliding member 142 moves forward or backward along the guiding part 143 for sliding member, the third ratchet 1422 of the sliding member 142 is engaged with the first ratchet 1451 to drive rotation of the first ratchet 1451 and to indirectly drive rotation of the second ratchet 1452 that is spaced from the third ratchet 1422. In the present embodiment, there are two first ratchets and two third ratchets (two mating pairs) and one second ratchets. In alternative embodiments, the number of the first, second and third ratchets can vary based on weight and other limitations.

[0039] The second fixing member 144 in this example is different from the one in the first embodiment. The second fixing member 144 in this example comprises a location part 1448 adapted for engaging with the second ratchet 1452 (teeth of the ratchet) to stop sliding of the sliding member 142. A location supporting part 1449 is mounted at the back of the housing 111 to support the location part 1448. In particular, the location part 1448 has a first horizontal protrusion 14481. The location supporting part 1449 has a first supporting opening 14491 for allowing the first horizontal protrusion 14481 to insert therein and support the first horizontal protrusion 14481 (as shown in Figures 17A and 19A through 19D).

[0040] As shown in Figures 17A and 18, the second fixing member 144 further comprises a lifting handle1450 and a supporting part 1460 for the lifting handle which are adapted for controlling engagement or separation of location part 1448 and the second ratchet 1452, thereby stopping or allowing movement of the sliding member 142. In particular, the lifting handle 1450 comprises a holding part 14501 (or handle holding part 14501), a location engaging part 14502, and a lifting handle groove 14503 located between the location engaging part 14502 and the holding part 14501. The location engaging part 14502 is configured to engage with the location part 1448 through a connection part 14504. The supporting part 1460 for the lifting handle is mounted at the back of the housing 111 and comprises a second supporting opening 14601 disposed opposite to the first supporting opening 14491 and a groove engaging part 14602 disposed in the second supporting opening 14601. The second fixing member 144 further comprises a fourth spring 1453 (or lifting handle spring) disposed between the location part 1448 and the supporting part 1460 for the lifting handle. When the location part 1448 is engaged with the second ratchet 1452 (as shown in Figures 19A and 19B), the first supporting opening 14491 allows the first horizontal protrusion 14481 to insert therein and support the first horizontal protrusion 14481. The second supporting opening 14601 allows the location engaging part 14502 to insert therein. The groove engaging part 14602 is engaged with and supports the lifting handle groove 14503. The location engaging part 14502 can be moved upwardly to separate the location part 1448 from the second ratchet 1452 and separate the groove engaging part 14602 from the lifting handle groove 14503. The location engaging part 14502 can be supported on the top of the groove engaging part 14602, thereby allowing the sliding member 142 to slide forward or backward along the guiding part 143 for the sliding member.

[0041] In an alternative embodiment, the lifting handle and the supporting part for the lifting handle are omitted and replaced with any other suitable parts can be used to control engagement or separation of the location part with/from the second ratchet. In addition to the combinations that include the first embodiment of the adjusting assembly and the first embodiment of the supporting assembly (shown in Figure 1) and that include of the third embodiment of the adjusting assembly and the second embodiment of supporting assembly (shown in Figure 7), any embodiment of the adjusting assemblies set forth herein can be combined with any embodiment of the supporting assemblies set forth herein.
